TREADLE FOR SEWING MACHINE MOTORS. 10.257.005 Patented Apr. 2\5.1882.

UNITED STATES PATENT OEEIcE.

i GEORGE A. HEATH, OF WIAUPUN, WISCONSIN.

SPECIFICATION forming part of Letters Application filed March 15, 18S-2.

To all whom it may concern:

Be it known that I, GEORGE A. HEATH, of Waupun, in the county ot' Dodge and State of Wisconsin, have invented certain Improvements in Treadles for Sewing-Machine Motors, of which the following is a specification.

My invention relates to a treadle designed for use in connection with the sewing-machine motor for which Letters Patent were granted to R. L. Vhitehill March 2, 1880, numbered 225,191, to which reference is hereby made for details thereof not shown herein.

The invention consists in a treadle composed ot' two parts--one connected with the lever by which the machine is connected with or disconnected i'rom the driving-power, the other overlapping the rst at the forward side or edge, and connected with the presser-foot of a sewing-machine, so that by depressing the forward edge of the compound treadle the machine is put in motion, while by depressing the rear edge or side thereot' it is disconnected from the driving-power, and by simply depressing the rear edge or side of one section the presser-foot is raised without stopping the machine.

In the accompanying drawings, Figure l represents a perspective view of myimproved treadle; Fig. 2, a view showing the detachable lever or arm.

Heretotore a separate trcadle or foot-piece, located at a distance of about twelve inches from the main treadle, has been provided to control the presser-foot; but such arrangement is objectionable in that it requires the operator to move his foot from the treadle about a foot to the right each time the presser-foot is operated, and then to move it back to the Jnrstposition. My invention is designed to overcome this difficulty, and with this end in view I construct my improved treadle as represented in the drawings, in which- Aindicates the main treadle, by which the friction-wheel C, which establishes connection between the driving-power and the sewingmachine, is thrown into or out ofcontact with the friction-plate D; and B, the second section or treadle by which the presser-foot is controlled.

As shown, the treadle-section A is formed Patent No. 257,005, dated April 25, 1882.

(No model.)

The section or treadle B is provided with an arin,c, which connects with the elevating-lever"`\ ot' the presser-foot of the sewing-machine.r

The forward end of the section B overlaps the arm a, so that by pressing upon the forward side of the section B it will be caused to assist in depressing said arm and in throwing and holding the friction-wheel against the ldiskD; but the rear end ofthe section or treadle B may be depressed to elevate the presser-foot without in any way affecting the treadle A.

In order to operate the presser-foot lever, it is necessary to depress the rear edge of` section B about an inch lower than section A can be depressed, as is the case with other devices of this character now in use.

In order to adapt the treadle to use with dry-thread machines as well as those employing waxed thread, the presser-foot being operated by different means in the former class of machines, the arm c of treadle-section B is made readily detachable, being formed with hooks or lugs d, which engage over the web or body of the treadle, as in Fig. 2, andasingle fastening-screw, c, being passed through its inner end and into the body of treadle B.

By removing the screw e the arm c may be taken oft.

When the arm c is not used the treadles A and B may be firmly connected by a screw, f, a turn-button or equivalent fastening passing through the forward edge of section B and into the arm a, as shown, thus making the two treadles one in effect.

I am aware that a lever has been placed by the side of a sewin g-machine-operatin g treadle, to which the operators foot Inay be shifted or turned for the purpose of controlling the presser-foot, and this I do not claim.

By my construction and arrangement the operator is enabled to control the machine without shifting his feet at all, thus addingto the facility and certainty of control.

IOO

The treadle may he applied to other motors which are similar in construction to the one shown and described.

Having thus described my invention, what I claim isfl. A treadle for use in connection with a motor, substantially such as referred to, consisting of the section A, having thel arm ci connected with the shifting-lever of the motor, andthe section B, overlapping arm a' and connected with the presser-foot lever of a sewing-machine, as set forth.

2. The herein-described treadle, consisting,` of sections A B, connected respectively with the shifting or clutching,` lever of a motor and with thc presserfoot lever of a sewing-machine, and adapted, substantially as described,

to be operated both independently and in unison, as and for the purpose explained.

3. In combination with the treadle A, having arm a, the trcadle B, overlapping said arm, and provided with t-hedetacliable arm c and screw or fastening f, as and for the purpose sct forth.

4. 1n combination with the treadle B, the arm c, provided with lugs or hooks d, andthe fastening-sore.` e, as and for the 4purpose set forth.
